To all 'whom t mai/ concern:

Beit known that I, HARRY L. HUssMANN,

. a citizen of the United States, and residing at St. new andvuseful Improvement in Showcase Refrigeratorsfof which the following is a specifica-tion.

This -invention relates to' a refrigerator, and more particularly to show case refrigerators, such Pas' disclosed 1n Patent No.

1,225,682, patented May`8, 1917, and which 1s provided with a container for the vrefrigerant or freezing mixture, mountedusually at'one end, and which communicates with a cooling chamber or show case, provision being made for the circulation of' air about the refri erant container and through the cooling c 'amber or show case.

One of the Aobjects of this invention is to provide simple and convenient means for removing the refrigerant container.

Another object is to provide such means for removing the container through a side door, and in such a way as not to interfere with the air circulation system.

Another object of this invention is to provide'a pan mounted and arranged for catching the drip from the container when the latter is moved out of the refrigerator.

Further'objects will appear from the detail description taken in connection withthe accompanying drawing, in which:

Figure 1 is a 4rear elevation showing a show case refrigerator embodying this invention;

Figure ure 1;

Figure 3 is a detail showing 4the method of securing the pan;

Figure 4 is a detail showing the construction of the hingefor the pan;

' Figure 5 is a. view in elevation of the structure of Figure 4; and" Figure 6 is a section on line 6-6, Figure 5. Y v

Referring to the accompanying drawing, the refrigerator comprises the usual .cooling chamber or shoa7 case 1 and a chamber or compartment 2 for housing the refrigerant container, from which the drippings fall. A side door 3 is 'provided -for the removal of the container. The door 3, in this case,l

24 is a section on line 2-2, Figswings on a vertical axis on hinges 4. PWith- Louis, Missouri, have invented the,

y8 vare preferably constructed of the air therethrough as shown 1n said patent.

The container `5 may be provided with rollers 7 arranged to run .on` a pair of rails 8 mounted on supports 9 on the interior of the chamber 2. The rails 8 are arranged transversely of the chamber 2 and in such a Way that the container 5 may be moved therealong and out of the door 3. The rails angle iron which` may be equipped with a sheetv iron. trough 10 as shown in Figure 6 so as to prevent the rollers 7 from leaving the rails.

Hinged at 11 to the ends ofthe rails 8 are a pair of extension rails 12 having permanently attached thereto and adapted to support a pan 13 so as to bemovableftherewith. The hinges 11 are located just with in the door 3 and therails 12 and thepan 13 are arranged so that when the door 3 is open, the'p'an may be inges 11 until the rails 12 restv upon the door sill 14V and the pan will be supported in` a horizontal position extending throudh the door Way, as shown in dotted lines in Figure 2. When the pan is lowered inv this position, the container 5 may be run out .upon the rails 12 and over the pan 13 to the dotted line position Figure 2 from. which position it may be easily removed from the `refrigerator. The pan 13 is equipped with Sti' 12 and run into the chamber 2. After this is done, the rails and pan13 are raised on the hinges 11 to the full line position in Figure 2, with lthe pan in the door-Way and against the container. It may be latched in this position by meansv of a latch 16 engaging a. depression 17 in the top of. the chamber 2.

It will be seen thatthe. container may be removed from the refrigerator by means of this device in a very simple and efficient manner. The door 3 being placed 'at the side may vbe opened without interference with the circulating air currents. When the pan 13 is lowered, the container may quickllO . in'and e door-way therefor, and inea-ns forV 1y be run out to e, position convenient for handling' and een he as eiisiiy und quickly returned. "W hen not in use, the pen 13 foldsy into e email speee where it isout of the way.

It is obvious that various changes may be made in details' of construction without depitrtin -from the spirit of this invention; itiisgt erefore, to he understood that. this invention is not to be iiinited to the Speeiie detaiisshown und deserihed.

Having thus described the invention, what is claimed is:

1. In a show-oase refrigerator. having a Compartment, a, refrigerant container thereguiding said container for movement into and ont ot seid compartment, including e, pen mounted onmovement into end ont of seid doorway.
